2nd Generation Barracuda Trivia

I bought my first Barracuda in 1979 , I was 18 going 19 . It was a 1969 318 notch back.
And that is what it was called back then a notch back. so the term has been around a long time. I also figured it was the look, like previously said , some one took a fastback
and cut a notch out of her.
